What is tesamorelin?

Tesamorelin is a lab-made version of growth hormone–releasing hormone (GHRH), the signal the brain sends to tell the pituitary gland to release growth hormone. Branded tesamorelin is approved for one narrow use, reducing excess belly fat in adults with HIV-associated lipodystrophy. Compounded tesamorelin is different from an FDA-approved product: it is not FDA-approved.

These articles cover how tesamorelin works, what its clinical trials measured, side effects, and how it compares with other growth-hormone peptides. It is prescription-only: a licensed provider reviews every request, and not everyone qualifies.

    Tesamorelin Dosage: How Prescribers Set It

    Tesamorelin is dosed daily in the trials and current brand label, but the milligram amount depends on the formulation. IGF-1, glucose, indication and tolerability matter more than a copied schedule.
